五指山市森林植被碳储量空间分布特征

Spatial Distribution of Forest Vegetation Carbon Storage in Wuzhishan City,China

依据五指山市2010年森林资源二类调查数据,运用生物量换算因子连续函数法估算五指山市森林植被碳储量,借助地理信息系统技术分析其空间分布特征。结果表明:五指山市森林植被总碳储量6060938.32 t,平均碳密度52.22 t·hm^(-2);各乡镇、林场、农场和自然保护区的森林碳储量与面积大小不成正比;乔木林碳密度分布规律为:水土保持林>国防林>水源涵养林>自然保护林>一般用材林>林化工业原料林>短轮伐期用材林>药用林>果树林>食用原料林;樟树林>杂木林>阔叶混交林>松类>杉木林>热带林>桉树林;天然林>人工林;过熟林>近熟林>成熟林>中龄林>幼龄林;高郁闭度>中郁闭度>低郁闭度;自然度Ⅱ级>Ⅰ级>Ⅲ级>Ⅳ级>Ⅴ级。

In this paper, based on Wuzhishan 2010 Forest Resource Inventory data, using the amount of conversion factor function estimates Wuzhishan forest carbon storage, using GIS analyze the spatial distribution. The results show that the number of total carbon storage is 6060938.32 t,the average carbon density is 52. 22 t · hm^-2. The storage,township,farms and nature reserves,is not proportional with the area Arbor carbon density distribution is that Water Conservation Forest 〉 Defense Lin 〉 Water Conservation Forest 〉 Conservation forest 〉 General Wood 〉 Forest chemical raw material forest 〉 Short Rotation Timber 〉 Medicinal Forest 〉 Fruit trees 〉 Consumption of raw material forest, Camphor forest 〉 mixed forest 〉 broadleaf forest 〉 coniferous 〉 Chinese fir 〉 tropical forest 〉 Eucalyptus, Natural 〉 Plantation, mature forest 〉 nearly mature forest 〉 mature forest 〉 middle-aged forest 〉 young forest, Dense canopy closure 〉 in canopy density 〉 sparse canopy closure, naturalness Ⅱ 〉 naturalness Ⅰ 〉 naturalness Ⅲ 〉 naturalness Ⅳ 〉 naturalness Ⅴ.
